Paste your CSS and minify it instantly. Removes whitespace, comments, and redundant semicolons. See exactly how much file size you save.
Paste your CSS code into the input area and click "Minify CSS". The tool will instantly remove all unnecessary characters including whitespace, comments, and redundant semicolons. You can then copy the minified output or download it as a .css file.
The CSS minifier parses your stylesheet and removes:
• Whitespace (spaces, tabs, line breaks)
• CSS comments (/* ... */)
• Redundant semicolons and properties
• Empty CSS rules
This reduces file size without changing how your styles work, leading to faster page load times.
